SunFounder GalaxyRVR Kit for Arduino, Release 1.0
Just as our neck muscles move our head so our eyes can get a better view, the servo will move the tilt mechanism so the
Rover’s camera can better survey the Martian landscape.
So, buckle up, explorers, let’s start our mission to equip our Rover with its very own visual system!
3.10.1 Objective
• Practice installing and operating the tilt mechanism on the Mars Rover model.
• Understand the principles of operation and application of servo.
• Learn how to control servo movement through Arduino programming.
3.10.2 Materials
• Arduino UNO development board
• Servo
• Gimbal and camera
• Mars Rover model (already equipped with TT motor, suspension system, ultrasonic and infrared obstacle avoid-
ance modules, RGB LED strip)
• Arduino IDE
• Computer
3.10.3 Steps
Step 1: What is a Servo?
Have you ever watched a puppet show? If you have, you might have marveled at how the puppeteer can make the
puppet’s arms, legs, and head move so smoothly, just by pulling on some strings. In a way, servo motors are like our
puppeteers.
